The process of an Office Supply Request starts when any employee of the organization submits an office supply request.

Once the requirement is registered , the request is received by the immediate supervisor of the employee requesting the office supplies.

The supervisor must approve or ask for a change , or reject the request.

If the request is rejected the process will end.

If the request is asked to make a change then it is returned to the petitioner / employee who can review the comments for the change request.

If the request is approved it will go to the purchase department that will be in charge of making quotations ( using a subprocess ) and select a vendor.

If the vendor is not valid in the system the purchase department will have to choose a different vendor.

After a vendor is selected and confirmed , the system will generate and send a purchase order and wait for the product to be delivered and the invoice received.

In any case the system will send a notification to let the user know what the result was.

In any of the cases , approval , rejection or change required the system will send the user a notification .
